2336-610: The Neolithic but was originally used in the preceding Mesolithic in some areas such as Ireland. Agriculture fed larger populations, and the transition to sedentism allowed for the simultaneous raising of more children, as infants no longer needed to be carried around by nomads . Additionally, children could contribute labor to the raising of crops more readily than they could participate in hunter-gatherer activities. With this increase in population and availability of labor came an increase in labor specialization . What triggered

2409-677: The Palace of Knossos. Several Minoan private homes also had toilets, which could be flushed by pouring water down the drain. The ancient Romans had many public flush toilets, which emptied into an extensive sewage system . The primary sewer in Rome was the Cloaca Maxima ; construction began on it in the sixth century BCE and it is still in use today. The ancient Romans also had a complex system of aqueducts , which were used to transport water across long distances. The first Roman aqueduct

2482-471: The Paleolithic era include clothing and shelter. No consensus exists on the approximate time of adoption of either technology, but archaeologists have found archaeological evidence of clothing 90-120 kya and shelter 450 kya.

Measures of technological innovation correlates with a rise in greenhouse gas emissions. Pollution, the presence of contaminants in an environment that causes adverse effects, could have been present as early as the Inca Empire . They used a lead sulfide flux in

2920-490: The belief that technological development is a moral good , which can and should bring about a utopia , that is, a society in which laws, governments, and social conditions serve the needs of all its citizens. Examples of techno-utopian goals include post-scarcity economics , life extension , mind uploading , cryonics , and the creation of artificial superintelligence . Major techno-utopian movements include transhumanism and singularitarianism . The transhumanism movement

2993-557: The city-state of Ur dates to around 3,429 BCE, and even older fragments of wheel-thrown pottery have been found in the same area. Fast (rotary) potters' wheels enabled early mass production of pottery, but it was the use of the wheel as a transformer of energy (through water wheels , windmills, and even treadmills) that revolutionized the application of nonhuman power sources. The first two-wheeled carts were derived from travois and were first used in Mesopotamia and Iran in around 3,000 BCE. The oldest known constructed roadways are

Some researchers have warned against

3358-553: The first stone tools by hammering flakes off a pebble, forming a sharp hand axe . This practice was refined 75 kya (thousand years ago) into pressure flaking , enabling much finer work. The discovery of fire was described by Charles Darwin as "possibly the greatest ever made by man". Archaeological, dietary, and social evidence point to "continuous [human] fire-use" at least 1.5 Mya. Fire, fueled with wood and charcoal , allowed early humans to cook their food to increase its digestibility, improving its nutrient value and broadening

3431-517: The fur and hides of hunted animals, helped humanity expand into colder regions; humans began to migrate out of Africa around 200 kya, initially moving to Eurasia . The Neolithic Revolution (or First Agricultural Revolution ) brought about an acceleration of technological innovation, and a consequent increase in social complexity. The invention of the polished stone axe was a major advance that allowed large-scale forest clearance and farming. This use of polished stone axes increased greatly in

As technology has advanced, so too has the negative environmental impact, with increased release of greenhouse gases , including methane , nitrous oxide and carbon dioxide , into

4599-454: The role and use of technology, the ethics of technology , and ways to mitigate its downsides are ongoing. Technology is a term dating back to the early 17th century that meant 'systematic treatment' (from Greek Τεχνολογία , from the Greek : τέχνη , romanized :  tékhnē , lit.   'craft, art' and -λογία , 'study, knowledge'). It is predated in use by

4672-537: The stone-paved streets of the city-state of Ur, dating to c.  4,000 BCE , and timber roads leading through the swamps of Glastonbury , England, dating to around the same period. The first long-distance road, which came into use around 3,500 BCE, spanned 2,400 km from the Persian Gulf to the Mediterranean Sea , but was not paved and was only partially maintained. In around 2,000 BCE,

4745-476: The time, Technologie (German and French) referred either to the academic discipline studying the "methods of arts and crafts", or to the political discipline "intended to legislate on the functions of the arts and crafts." The distinction between Technik and Technologie is absent in English, and so both were translated as technology . The term was previously uncommon in English and mostly referred to

4818-527: The use of robotic soldiers, algorithmic bias , and the issue of aligning AI behavior with human values. Technology ethics encompasses several key fields. Bioethics looks at ethical issues surrounding biotechnologies and modern medicine, including cloning, human genetic engineering, and stem cell research. Computer ethics focuses on issues related to computing. Cyberethics explores internet-related issues like intellectual property rights , privacy , and censorship . Nanoethics examines issues surrounding

4891-506: The value judgments that shape technology. Cultural critic Neil Postman distinguished tool-using societies from technological societies and from what he called "technopolies", societies that are dominated by an ideology of technological and scientific progress to the detriment of other cultural practices, values, and world views. Herbert Marcuse and John Zerzan suggest that technological society will inevitably deprive us of our freedom and psychological health. The ethics of technology

4964-527: The widespread application of the factory system . This was followed a century later by the Second Industrial Revolution which led to rapid scientific discovery, standardization, and mass production. New technologies were developed, including sewage systems , electricity, light bulbs , electric motors , railroads, automobiles , and airplanes. These technological advances led to significant developments in medicine, chemistry , physics , and engineering. They were accompanied by consequential social change, with

5037-529: Was "freed from societal deformations". Second-wave philosophers like Ortega later shifted their focus from economics and politics to "daily life and living in a techno-material culture", arguing that technology could oppress "even the members of the bourgeoisie who were its ostensible masters and possessors." Third-stage philosophers like Don Ihde and Albert Borgmann represent a turn toward de-generalization and empiricism, and considered how humans can learn to live with technology. Early scholarship on technology

5110-574: Was built in 312 BCE. The eleventh and final ancient Roman aqueduct was built in 226 CE. Put together, the Roman aqueducts extended over 450 km, but less than 70 km of this was above ground and supported by arches. Innovations continued through the Middle Ages with the introduction of silk production (in Asia and later Europe), the horse collar , and horseshoes . Simple machines (such as

5183-513: Was compensated by the creation of new, higher-paying jobs. Studies have found that computers did not create significant net technological unemployment . Due to artificial intelligence being far more capable than computers, and still being in its infancy, it is not known whether it will follow the same trend; the question has been debated at length among economists and policymakers. A 2017 survey found no clear consensus among economists on whether AI would increase long-term unemployment. According to

5256-536: Was probably used from near the beginning of Neolithic times (about 10 kya). Native copper does not naturally occur in large amounts, but copper ores are quite common and some of them produce metal easily when burned in wood or charcoal fires. Eventually, the working of metals led to the discovery of alloys such as bronze and brass (about 4,000 BCE). The first use of iron alloys such as steel dates to around 1,800 BCE. After harnessing fire, humans discovered other forms of energy. The earliest known use of wind power

5329-649: Was split between two arguments: technological determinism , and social construction . Technological determinism is the idea that technologies cause unavoidable social changes. It usually encompasses a related argument, technological autonomy, which asserts that technological progress follows a natural progression and cannot be prevented. Social constructivists argue that technologies follow no natural progression, and are shaped by cultural values, laws, politics, and economic incentives. Modern scholarship has shifted towards an analysis of sociotechnical systems , "assemblages of things, people, practices, and meanings", looking at
